Just bought an airaid CAI mated with a K&N cone filter and I have a few things to say. First of all I'm pleased so far in my first day driving with it, I really felt and heard the difference at high revs getting on the freeway this morning, but it didn't come with a heat shield. Should I make one or rig something up using the factory air box? Does anyone know how well the factory box works at blocking heat and if I can't manage to fit these parts together what would be a good material to make a homemade heat shield or air box with? Also, in my 1997 c1500 p/u with 5.0L vortec V8, is the black box sitting atop the intake and throttle body the resonator (the on that says VORTEC) on it? if so can that be removed to remove some resistance? I know about aftermarket tubing kits and am choosing not to go that route right now Thanks for any input and pictures of homemade heat shields for aftermarket CAIs!
